Under first-year coach Chip Kelly, the Philadelphia Eagles are expected to deploy tight ends in ways they never had before.

We could see two and three-tight end sets, use of the H-back, tight ends lined up in the slot or split out wide. With their versatility, there's seemingly no end to the wrinkles they can bring to the Eagles' offense.

And Kelly has made depth a priority at the position with the acquisition of free agent James Casey and selection of Zach Ertz in the second round of the NFL draft.

Casey is a Swiss Army knife in his own right, a unique athlete who can line up just about anywhere. Ertz was one of the best tight end prospects in the nation as an outstanding receiver and blocker.

They'll complement veteran stalwart Brent Celek, who returns as the projected starter after piling up consistent production in his seven seasons with the Eagles.

Add it all up, and you've got one of the Eagles' deepest, most dynamic positions. Here's a look at the projected starters, key reserves and new faces to watch as training camp begins later this month.

PROJECTED STARTERS

Brent Celek: Celek has been a consistent and productive part of the Eagles offense since being selected in the fifth round of the 2007 NFL draft. Celek has averaged 59 catches and 744 yards over the last four seasons, the highlight being a 971-yard, eight-touchdown campaign in 2009. While the most accomplished of the Eagles' tight ends, Celek is also the only player that first-year coach Chip Kelly didn't hand-pick. If depth materializes around him, Celek could find himself the subject of trade rumors.

James Casey: Casey was the Eagles' first order of business during the NFL's free agency period. He was signed to a three-year, $14.5 million deal after spending four seasons with the Houston Texans. He underwent minor surgery on his right knee in May, but is expected to be ready for training camp. Casey will play the H-back position for the Eagles as a hybrid fullback and tight end, and he has the career credentials to support such a versatile role. He has played quarterback and wideout, as well as three seasons of minor league baseball. He's been called a "very gifted athlete, very smart" by Texans tight ends coach Brian Pariani.

KEY RESERVES

Clay Harbor: Harbor experimented at outside linebacker during OTAs and could be in line for an official position change. Or he could provide depth on both sides of the ball. Either way, Harbor is unlikely to be a factor at tight end, barring a rash of injuries.

Emil Igwenagu: Igwenagu is built for the H-back position with collegiate experience as a fullback, running back, tight end and linebacker. He saw time late last season as a fullback after spending the first 14 weeks on the practice squad.

Derek Carrier: Carrier spent most of last season on the Eagles' practice squad after initially being signed by the Oakland Raiders. He played collegiately at Division III Beloit College, where he set multiple school records as a wide receiver.

NEW FACES TO WATCH

Zach Ertz: Kelly was plenty familiar with Ertz before taking him in the second round of the 2013 NFL draft. Ertz played a key part for a Stanford team that dashed Kelly's chances at a national championship at Oregon. He's a well-rounded tight end who can block and be a force in the team's passing game. Ertz could supplant Celek as the team's starter in the not-so-distant future.

Will Shaw: The Eagles signed Shaw after Casey underwent knee surgery. He's a safety-turned-tight end who finished his career at Youngstown State with 43 catches for 629 yards and eight touchdowns.

KEY LOSSES

Stanley Havili: Havili, a fullback, was traded to the Indianapolis Colts in March. Originally drafted by the Eagles in 2011, Havili was made expendable because Kelly's offense will operate without a traditional fullback.
